Key inclusion & exclusion criteria
Inclusion criteria:

PAH associated systemic sclerosis, PAH following one year repair of congenital heart defect (ASD, VSD or PDA), or PAH associated with diet therapies or other drugs
3) A PVR =800 dynes.sec.cm-5 despite treatment with two or more specific PAH therapies, including endothelin receptor antagonists (ERA), phosphodiesterase 5 inhibitors (PDE5), or subcutaneous, inhaled, intravenous or oral prostacyclin analogues for = 3 months. Background therapy doses must be stable for = 30 days except for warfarin and prostacyclin analogues ( = 30 days but doses can vary even within the month before enrollment)
4) WHO Functional Class II-IV. For WHO Functional Class IV, one of the 2 or more specific PAH therapies must be an inhaled, subcutaneous, intravenous or oral prostacyclin analogue, unless the subject has been shown to be intolerant of prostacyclin analogues.
5) 6MWD = 150 meters and = 450 meters at screening. Distances of two consecutive 6MWTs should be within 15% of one another.
6) Ability to provide written informed consent by the patient or a legal guardian

Primary Outcome(s)
Main Objective: • To evaluate the efficacy of QTI571 compared to placebo as measured by the change in 6-minute walk distance (6MWD) from baseline to 24-weeks
Primary end point(s): • 6MWD – a marker of exercise tolerance (the distance walked in 6 minutes during a 6-minute walk test according to ATS guidelines)
Secondary Objective: • To evaluate the time to clinical worsening (TTCW), defined as all cause mortality, overnight hospitalization for worsening PAH (established by external adjudication committee), worsening of WHO functional class or a drop in 6MWD by 15% during 24 weeks of treatment with QTI571 as compared to placebo
• To assess changes in health-related quality of life after 24 weeks of treatment (using CAMPHOR) with QTI571 compared with placebo
• To assess the safety and tolerability of QTI571
• To evaluate change in pulmonary hemodynamics from baseline in patients after 24 weeks of treatment with QTI571 as compared to placebo
• To assess change in Borg dyspnea score during 6MWT, monthly, with QTI571 as compared to placebo.
• To assess the pharmacokinetics of QTI571 and the potential for interaction of QTI571 on sildenafil and bosentan
• To assess the pharmacogenetics of QTI571
• To assess the use of different possible definitions of time TTCW as a measure of efficacy in treatment of PAH
